COMPANION VALVE<br />
Hattersley highly recommends the use of a companion<br />
valve as a part of the circuit. As well as providing<br />
standard flow measuring and regulating features, the<br />
companion valve has an integral tapping point for an<br />
impulse tube to link the valve and the DPCV.<br />
Additional impulse tubes are available on request.<br />

ISOLATING BALL VALVE<br />
DPCV ACCESSORIES<br />
Installing a ball valve in the impulse tube<br />
allows isolation of the tube during flushing.<br />
This helps to ensure that the tube is kept<br />
free from debris.<br />
MALE & FEMALE TAILPIECES<br />
Hattersley offers additional male and female<br />
BSP taper threaded couplings, giving the<br />
contractors a variety of options on installation<br />
and enabling a fast and easy connection to<br />
the pipe work.<br />
